• Package Name: azure-identity
• Package Version: 1.6.1

• Package Version: 2.2.0
• Operating System: Windows 10 Home 19042.1237
• Python Version: 3.9.5

Describe the bug
After creating a resource management client, when trying to use it to return a list of resource groups (or similar code to create a new resource group), the code fails with an attribute error "'ClientSecretCredential' object has no attribute 'signed_session'."

To Reproduce
Steps to reproduce the behavior:

1. Define environment variables for a service principal with Contributor role to the Azure Basic subscription.
2. Run the code below.
3. Results in the error message: "AttributeError: 'ClientSecretCredential' object has no attribute 'signed_session'"

import os
from azure.mgmt.resource import ResourceManagementClient
from azure.identity import ClientSecretCredential

def main():
    SUBSCRIPTION_ID = os.environ.get("AZURE_SUBSCRIPTION_ID", None)
    tenant_id = os.environ["AZURE_TENANT_ID"]
    client_id = os.environ["AZURE_CLIENT_ID"]
    client_secret = os.environ["AZURE_CLIENT_SECRET"]
    credential = ClientSecretCredential(tenant_id=tenant_id, client_id=client_id, client_secret=client_secret)

    print("Create resource client...")
    resource_client = ResourceManagementClient(credential, SUBSCRIPTION_ID)
    print("Printing existing resource grouops:")
    for item in resource_client.resource_groups.list():
        print_item(item)

if __name__ == "__main__":
    main()

This code results in the following output:

Create resource client...
Printing existing resource grouops:

    self._creds.signed_session(session)
AttributeError: 'ClientSecretCredential' object has no attribute 'signed_session'

Expected behavior
Expect the code to return the list of existing resource groups.

Screenshots
N/A

Additional context
Similar code has worked previously when I ran it in an Ubuntu (20.04) virtual machine, but I do not have access to this VM anymore. I'm now trying to run this code in a venv virtual environment in a PyCharm Community project, running PyCharm on a Windows 10 laptop (same laptop in which the Ubuntu VM was run). The same service principal was used when it worked on Ubuntu VM.

Thanks for your feedback.

azure-mgmt-resource 2.2.0 is track 1 library and it is not fully compatible with azure-identity.

You can upgrade azure-mgmt-resource to latest version or https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/identity/azure-identity/migration_guide.md for migrations.

Please let us know if any questions.

Thanks for the quick response. Switching to azure-common credentials, as detailed in the link, did indeed fix the issue.
